PHILLIP SHERIDAN KIRBY, OF DENVER, COLORADO.

EMBROIDERY-NEEDLE.

Specification of Letters Patent.

Patented Nov. 15,1921.

Application filed April 13, 1920. Serial No. 373,584.

To all whom it may concern: 1 Be it known that I, PHILLIP SHERIDAN KIRBY, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have lnvented certain new and useful Improvements in Embroidcry-Needles; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to art needles or embroidery needles, and more especially to such rately and precisely regulating the depth of needle penetration, and consequently the extent of loops formed upon the under side of the fabric base.

A further object is that of combining with art needles of the class described an adjustable tension element for producing more or less tension upon the embroidery thread during the operation.

, A further object is the production of improved needles of the character indicated consisting in the novel construction, arrangement and combination of parts shown by the drawings forming part of the present application, hereinafter described.

In the drawings herewith submitted and whereon corresponding characters refer to like parts in the several views:

Figure 1 is a side elevation of my present invention threaded and ready for use;

Fig. 2 is a longitudinal central section thereof;

Fig. 3 is a top plan view of the same;

Fig. 4; is a rear view;

Fig. 5 is a transverse section taken on the line 55 of Fig. 1; and

Fig. 6 is a detail detached view in perspective of a combined depth gage and tension spring.

Reference being bad to the drawings and numerals thereon, 1 indicates the needle body preferably constructed of sheet metal and of substantially tubular or hollow formation. This body portion 1 is substantially U- shaped 1n cross-section except at and near its upper end, where its-sides are crimped together as at 2, leaving however, an end thread openlng 3 therein. The sides of said body portion 1 moreover, present relatively wide flattened surfaces 41 and 5, in the latter pf which are two series of perforations one 1n transverse arrangement marked 6, and the other arranged longitudinally designated bythe numeral 7 both of said series being for purposes which will later appear.

Immediately'below the body 1 and integral therewith, is a hollow pointed needle 8 provided with an eye 9, in its lower end, this member being practically circular in cross section, while at approximately the point of juncture between said body 1 and needle 8, the back of the structure is broken by two thread openings 10, 10, the intervening metal being bent inward to form a tension bridge 11 over which the embroidery material or thread 12 is passed as shown by Figs. 1, 2 and 3, thus exposing the thread at that particular location to view.

Surrounding the needle 8 at a point below said bridge 11 is an adjustable depth gage 13, made of relatively stiff spring wire, which traverses one side of the needle in an upward direction as at 14, thence loops over the back of the structure as at 15, from which point it is continued upwardly parallel with flattened side 5 as at 16 terminating in an angular bend 17 adapted to enter one of the adjusting holes 6 or 7 for adjustment purposes as will now appear in a brief statement of use and operation.

Presuming that a needle has been threaded as indicated by Figs. 1, 2 and 3, the embroider material or thread 12 passes longitudinalliv therethrough, over the tension bridge 11 where it is exposed to view and through the eye 9 of the needle.

Presuming also that the combined depth gage and tension spring is set as indicated by Figs. 1, 2 and 8, it will be observed that the maximum of needle penetration is secured and that the loop 15 of the tension spring serves to bind the thread 12 upon bridge 11 with a moderate degree of pres sure, also that such pressure may readily be increased as desired for certain classes of embroidery, by simply withdrawing the angular end 17 of said spring from the first of said transverse perforations 6, and placing same in the second or third thereof according to the degree of tension desired.

As to the matter of longitudinal or depth adjustment, it is quite obvious that same is accomplished by similarly transferring the said angularextremity 17 to one or the other of the longitudinal holes 7 according to depth requirements.

The aforesaid adjustments having been made in accordance with the character and extent of the design to be produced, the threaded needle 8 is then passed rapidly through the fabric base (not shown) in the ordinary and well understood manner, each time leaving a suitable loop or stitch upon the underside of said base (not shown) as a part of the prearranged design to be subsequently trimmed with scissors or left untrimmed accordingto requirements of the particular design in the course of formation.

Having thus described one practical and successful embodiment of my present invention what I now claim and desire to secure by Letters Patent is An embroidery needle comprising in combination a tubular body and a pointed lower end, a tension bridge formed in said body member over which the embroidery thread must pass, a combined adjustable depth gage and tension spring arranged and adapted to cross said bridge transversely and to engage with its angular end either of a series of transverse holes in said body member.

In testimony whereof I aflix my signature, in presence of two subscribing witnesses.
